Can I enable triple buffering to (ForceFullCompositionPipeline = On) or enable fast sync instead of v-sync?

From answer here I unnderstand, that (ForceFullCompositionPipeline = On) is like global v-sync. Can I set triple buffering for that mode? Or change it’s behavior from v-sync to fast-sync?

I don’t think so. AFAIK, you can only turn it on or off but not modify its behaviour.
